I inspected the file and added _ALL_SOURCE=1:

...
checking whether the C compiler (gcc -ansi -D_ALL_SOURCE=1
-D_POSIX_SOURCE=1 -D_POSIX_C_SOURCE=200809L -Dinline= ) works... yes

Now tools/timer/main.c compiles as well as lib/gis/ls.c - hence the
types get defined.

Remains:
lib/gs/plot.c:34: error: conflicting types for 'nearest'
